WARM, DRY AND BREEZY CONDITIONS. THE PRIMARY CONCERN TODAY AND
TOMORROW WILL BE ELEVATED (TODAY) TO CRITICAL (THURSDAY) FIRE
WEATHER CONDITIONS. EXPECT HIGH TEMPERATURES IN THE 70S TO LOW
80S TODAY WITH WESTERLY WINDS GUSTING 15 TO 30 MPH (GREATEST WEST

LOW 90S. EXPECT BREEZIER CONDITIONS WEST OF BILLINGS ONCE AGAIN,
WITH GUSTS UP TO 40 MPH. A FIRE WEATHER WATCH IS IN EFFECT FOR
LOCATIONS WEST OF BILLINGS FROM NOON UNTIL 9 PM MDT ON THURSDAY.
PLEASE TAKE CARE NOT TO CAUSE A SPARK! A COLD FRONT LOOKS TO COME
THROUGH LATE THURSDAY OR EARLY FRIDAY MORNING, SHIFTING WINDS TO
THE NORTHEAST THROUGH FRIDAY.
FRIDAY INTO THE WEEKEND HAS MORE UNCERTAINTY AS A SYSTEM
APPROACHES. MODELS STILL DISAGREE ON THE EXACT TRACK AND INTENSITY
OF THIS SYSTEM. THIS SYSTEM LOOKS FAIRLY ROBUST WITH THE LATEST
TRACK FROM SEVERAL MODELS BRINGING IT THROUGH IDAHO AND INTO
SOUTHERN MONTANA. THIS TRACK LOOKS FAVORABLE FOR WIDESPREAD
PRECIPITATION AND MUCH COOLER TEMPERATURES. MOUNTAIN SNOWFALL
WOULD BE IN PLAY SO THOSE WITH PLANS TO RECREATION IN THE HIGH
COUNTRY SHOULD BE PREPARED. FOR NOW, WHAT IS CERTAIN IS A TREND
TOWARDS COOLER AND WETTER WEATHER TO END THE WEEK. LOOK FOR HIGH
TEMPERATURES TO BE IN THE 60S TO 70S FRIDAY AND SATURDAY, WHILE
50S AND 60S ARE CURRENTLY FORECAST ON SUNDAY.
OVERNIGHT TEMPERATURES ARE FORECAST TO DROP INTO THE MID 30S AND
40S, FRIDAY NIGHT THROUGH SUNDAY NIGHT. A FEW LOCATIONS MAY SEE
THEIR FIRST FROST OF THE FALL, WITH THE BEST CHANCE BEING MONDAY
MORNING. ALL FOOTHILL LOCATIONS CURRENTLY HAVE A 40 TO 60% CHANCE
OF A FROST MONDAY MORNING, WHILE AREAS WEST OF ROSEBUD COUNTY
HAVE A 15 TO 40% CHANCE. MATOS
